TypeError: expected a character buffer object

What steps will reproduce the problem?
1. Install 208-1 on Ubuntu
2. /usr/bin/mycheckpoint --defaults-file=/etc/mycheckpoint.cnf 
--skip-check-replication

What is the expected output? What do you see instead?

I get an error:

expected a character buffer object
--
-- Re-execute with --verbose --debug for detailed message and strack trace.

What is the output when running with the "--verbose --debug" options?

root@mysql:~# /usr/bin/mycheckpoint --defaults-file=/etc/mycheckpoint.cnf 
--skip-check-replication --debug
expected a character buffer object

    query = query.replace("${aggregation_timestamp}", aggregation_timestamp)
